In the previous days I have noticed that my charger only charges when I keep on moving the charger until today that it no longer works. It no longer charges the battery of my laptop though the LED light is emitting. This is also a common problem for laptop users, I have helped 4 of my friends and solved them all. If you have a problem with your laptop charger and have no budget in buying a new one I believe this post will help you.

As seen on the image above, the encircled part  is the point where most problems occur in a laptop charger.  This is caused when the wire is gradually pulled away from the laptop adapter box.  To start follow the steps below:

WARNING: This can cause electric shock if you don’t follow electronic safety tips.  Before you start I recommend reading some safety tips

1.  Gather the materials needed (ground strap, cutter knife, wire peeler, multi tester, scissor, loctite or similar and electrical tape)

2.  Wear the ground strap before starting to avoid any devices inside the laptop adapter box.

3.  Use the cutter knife and carefully trace open path found on the side of the charger until the cover separates.  (Most chargers are not screwed but rather permanently glued)

4.   When the cover is opened carefully cut the wires as seen on the image below and put aside the circuit.

5.  After cutting the wires use the multi-tester to check continuity on the inside and outside wires.  Cut the wire until there is continuity.

6.  After testing for continuity get the tip of the wire.  Remove the trailing wire and clean the hole where the wires are inserted as seen on the image below.

7.  Insert the newly cut wires both the shielded and unshielded stranded wires(must have continuity) and connect both wires

a is the unshielded wire and b is the shielded wire colored white.  Wires must not be interchanged because this can cause a damage on you laptop.

8.  Carefully connect the wire by twisting both ends.  Cover the connection with an electrical tape, using other tapes might melt because of the heat.  Below is how I taped the connection:

9.  Cover the “metal cover” of the the circuit with an electric tape to avoid any short circuits.  The unshielded wire might touch the conductor and can cause short circuit.

10.  Carefully insert the connected wires inside the metal cover and make sure the LED indicator is not covered.   Cover the circuit with the plastic adapter box as seen below:

My repaired laptop charger is now fully functional and I hope this will be working for 4 more years or more.  Hope this DIY helped you with your laptop charger problem
